it was a series of classroom kits slapped together. it was supposed to follow lines based on touch, light, distance, and ultrasonics, but the motor timing got jacked when i moved the brick into that chassis. ended up using that to battle others, with no weapons, against 2 other guys.

one of them got rammed and flipped, the other kamikaze'd himself

i'm in the process of converting it into a battle-ready set, though i'd have to rent out the kits to keep going.
